Quoted from EMpins16:Just picked up a TZ that has been sitting Unplayed for some time. It has some issues that seem to be a bit over my head as I am a novice to repair of games from this era. When the game turns on I get a switch 45 error ( mini playfield ) , click is broken error ( aware of the common problems with these ). The issue that has me stumped is that it immediately try’s to kick a ball out into the lane repeatedly , even though I haven’t started a game yet . It will just continue to do this until I power the game off . There are also credits on the machine but hitting the start button does nothing . Gumball machine is also empty . What could be causing this ? Any advice is greatly appreciated . Most of my repair experience is in EMs.
Sounds like:
You either have more than three balls in the trough and outhole (or, less or equal to three, and stuck switches!), AND,
your ball gate is not working, which is therefore kicking the ball into the shooter (assuming that is what you mean by 'into the lane').
The "Test Gumball" test is inherently useful here, and I recommend running it and taking a look at all your switches.
As 
ChrisHibler says, the game will only allow three balls in the trough at a time, so if a switch is stuck - or there are more balls than three, it will try to load the gumball. (And yes, by factory, the software assumes there is three balls in the gumball machine. The software will also assume that if a 4th ball appears in the trough, it needs to be loaded into the gumball machine.)
As this happens, you are also correct - you will not be able to start a game until the software is happy at the state of the balls.
